Patented nee. s, rare.

To all whom it may concern:

Be it known that I, JOHN P. NIKoNow, 'a subject of the Czar of "Russia,and a resident of Evansville, in the county of Vanderburg and State ofIndiana, have in vented a new and Improved Governor, of which thefollowing is a full, clear, and exact description.

My invention relates to governors, my more particular pur ose being toprovide an improvedtype 0 governor suitable for use upon turbines,acting by internal combustion or employing steam, air or vapor for theirpropulsion.

More particularly stated, my invention relates to improving the valvemechanism forming a partof the turbine and also improving the form bycentrifugal force,

of the weights operated and also improving the form of parts associatedwith these weights and with the valve controllable by the gov ernor.

Referenceis to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a vertical cross section upon the line 1-1 of Fig. 2,looking in the direc tion of the arrows and showing the turbine asarranged for operating an' electric generator, this view further showingthe governor connected with the turbine and with valves for controllingthe flow of the elastic fluid used for driving the turbine; Fig. 2 is areduced end elevation showing the turbine and its associated partsviewed as from n Fig. 1, the head of the casing containing'the governor,being removed; Fig. 3 is a horizontal sectionupon the line 3 3 of Fig.2, looking in the direction of the arrows and showing more particulai'lythe details of'the governor; and- -Fig. 41s a fragmentary section on theline 44 of Fig. 2, looking in the direction of the arrows, through thevalve which is con trolled by the centrifugal action of the gov ernor; I

Mounted upon feet 5 is a casing 6 closed by a head 7, held thereupon byaid of bolts 8. Integral with the head 7 and extending laterallytherefrom is a portion 9, containing a substantially cylindricalcompartment 9*, closed by a head 10. This head has generally the form ofa plate and is held upon the portion 9 by aid of bolts 11 which extendinto holes 12 Figs. 2 and '3.

The inlet pipe for the elastic fluid is shown at 13 and is provided witha coupling 14. The passage in the pipe 13 may be seen at 15 andregisters with a bore or passage 16, extending through a web 17, thelatter having some semblance to a cylindrical form, as will beunderstood from Fig. 2,'"being located within an opening 18 formed forthe sake of lightness, The passage-16 communicates with a valve cylinder19 which is provided with an enlarged portion 19 and is further providedwith ports as will be understood from 20, 21. Two pistons 22, 23 aremounted rig-- idly upon a piston rod 24 and spaced apart,

as indicated'ln Fig. 4:. Adjacent to the piston 22 the enlarged portion19* is provided with a wall 25 so that when the piston 22 occupies acentral position relatively to the enlarged portion 19 the elastic fluidcan readily find its way from the passage 16 through the-ports 20, 21,as indicated in Figs. land 4, and yet when the piston 22 is movedintocontact with the wall 25 so as to fit neatly within the cylinder 19,the

How of the elastic medium is affected accordingly.

The piston rod 24 is provided with a head 24? which is engaged by thelower end of a lever 26. This lever is journaled upon a bearing bracket27 the latter being secured upon a lug 28 supported by the framework.The lever 26 extends through a slot 26 and is adapted to work therein.Below the cylinder 19 is a compartment 29 for receiving the elasticfluid as the latter passes through the ports 20, 21. A nozzle 30 isscrewed directly into the frame and communlcates with the compartment-29. p

A hub 38 supports a disk 36 and extends through this disk, as indicatedin Fig. 1. The revoluble shaft 47, carrying the hub 38, is provided witha reduced portion 47 the latter having athread 47 A spider i9 isprovided with feet 49 which are secured to the disk36 by'aid of screws50. The sp der 49 engages the hub 38 directly. This spider is providedwith slots 51 so shaped as to form notches 51. The sider 49 is screwedupon the threaded end 4 b and is thus held in position, partly by itsconnectlon wlth the reduced portion 47 partly by the screws 50, andpartly by its direct engagement with the hub. The centrifugal weightsare shown at 52 and have each a general semicylindrical form. Eachweight is provided with a shouldered supporting arm 53, there being twoof these arms, one for each weight, and they extend into the slots 51.The shouldered arms 53 extend into the notches 51 and are thus securedin position while having a certain freedom or movement due tocentrifugal force.

Extending from the base 49 and integral therewith is a cylinder 54,which is partially encircled by the semicylindrical weights. As theslots 51 are located at the dividing line between the spider 49 and thecylinder 54, the slots may be considered as in the cylinder 54 as wellas in the spider. A head 55 having substantially the form of a disk ismounted loosely within the cylinder 54 and in-close proximityto theshouldered arms 53. A coiled-spring 56 engages the head 55 and alsoengages. a cap 58. Extending through this cap and journaled therein is arevoluble stub shaft 59. Mounted upon this stub shaft is a,nut 57 whichengages the head 55. terminates in a disk 60 which is disposed Within acup 61 containing a ball bearing 62, the latter having two sets ofballs, mounted. one set upon each side of the disk 60. y p

A cover 63 is provided for the cup 61 containin the ball bearing. Thecover 63 is pivota ly connected to the lever 26 by aid of a cotter pin'26". As the stub shaft 59 rotates, carrying with it the disk 60, thisdisk turns. within the cup 61, presenting comparatively little friction,owing to the action of the ball the cup.

The 0 eration of my device is as follows: An elastic fluid, such assteam, being admitted into the pipe 13, travels through the passage 16into the cylinder 19 and then, under ordinary conditions, passesdownwardly through both ports 20, 21, as indicated in Fig. 4. The spiralspring 56 being kept always partially under tension by the head 55, isnot free to yield except when an opposing pressure, greater than itsown, is applied to the head 55 in a direction opposite to that in whichthe spring 56 is pressing. As the centrifugal weights 52 fly outwardly,the arms 53 engage the head 55, and when the speed of rotation exceeds apredetermined limit, the pressure of the arms 53 a ainst the head 55becomes suflicient to move'this head slightly to the left according toFig. 3. This actuates the lever 26 and thereby shifts the position ofthepiston rod 24, causing the pistons 22, 23 to control the flow of theelastic fluid downwardly throu h the ports 20, 21. The pressure upon t%episton 23 is nearly balanced but is slightly The stub shaft 59 bearingcontained within unbalanced because of the difference in area of the twofaces of this piston, owing to the fact that the piston rod itself hassome little area in cross section. The action of the centrifugal weightsis sufiicient to control the position of the stub shaft 59 independentlyof the slight want of balance of the piston 23. If, however, the lever26 should break or become disconnected, there is no danger of theturbine running away, for the reason that the unbalanced pressure uponthe piston 23 drives the latter to the right, according to Fig. 4 (thatis, to the left according to Fig. 1) so as to stop the flow of theelastic medium through both ports 20, 21 and thus bring the machine to astandstill.

The double race ball bearing employed in connection with the disk. 60 isof great advantage, in that it enables the speed of the turbine to beincreased to'a high rate without in any way adversely affecting theaction of the governor.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent:

1. In a overnor, the combination of a shaft, a hu mounted thereupon,a-disk secured to said hub and revoluble therewith, a spider engagingsaid hub and provided with feet secured to said disk, said spiderengaging said hub directly and being provided with a cylindricalportion, centrifugally operated mechanism connected with saidcylindrical portion, a lever engaging said centrifugally operatedmechanism an actuated thereby, and a valve connected with said lever andcontrollable by motions of the same.

2. The combination of a disk, a hub pro vided with a portion extendingthrough said disk, a spider engaging said portion of said hub andprovided with feet engaging said disk, fastening 'members for securingsaid feet rigidly upon said disk, and governor mechanism connected withsaid spider and actuated by movements thereof.
